This is a sentence-transformers model finetuned from sentence-transformers/all-mpnet-base-v2. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("knguyennguyen/mpnet_jacket4k_enhanced")
# Run inference
sentences = [
    'enamel pin with a compact size, durable material, and a secure backing.. enamel pin with a compact size, durable material, and a secure backing.',
    'Title: Funny Chill Demon Enamel Pin Novelty Brooch Buttons Jewelry for Jackets Jeans Backpack Cloth Lapel Bag Hat Gift for Luci Fans Disenchantment Lovers Men Women Boy Girl Descripion: [\'-Size - About 1.2" -Hard enamel -Black shiny metal -One rubber clutch\']',
    "Title: Cute Cat Enamel Pin I LOVE ALL THE CATS Brooch Cartoon Animal Lapel Badge for Backpacks Jackets Clothes Bag Party Decoration Jewelry Gift for Friends Descripion: ['Cute Cat Enamel Pin I LOVE ALL THE CATS Brooch Cartoon Animal Lapel Badge for Backpacks Jackets Clothes Bag Party Decoration Jewelry Gift for Friends Cute Cat Enamel Pin I LOVE ALL THE CATS Brooch Cartoon Animal Lapel Badge for Backpacks Jackets Clothes Bag Party Decoration Jewelry Gift for Friends Cute Cat Enamel Pin I LOVE ALL THE CATS Brooch Cartoon Animal Lapel Badge for Backpacks Jackets Clothes Bag Party Decoration Jewelry Gift for Friends Cute Cat Enamel Pin I LOVE ALL THE CATS Brooch Cartoon Animal Lapel Badge for Backpacks Jackets Clothes Bag Party Decoration Jewelry Gift for Friends']",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
